Jun 3, 2015 · The term rock type is a more detailed description than lithology because it reflects the natural groupings of pore systems that produce recognizable properties used to predict: Flow properties; Volumes; Fluid saturations; Lithology focuses on grains, while rock type focuses on pores. The list of rock types contains more than 250 classifications. Intrusive rocks, also called plutonic rocks, cool slowly without ever reaching the surface. They have large crystals that are usually visible without a microscope. This surface is known as a phaneritic texture. Perhaps the best-known phaneritic rock is granite.
